cpufreq: intel_pstate: Debugfs file addition and cleanups

Hi all,

Below some work on intel_pstate driver.
Mostly a cleanup (patches 1/7, 5/7, 6/7, 7/7), some code simplification (patch 4/7) and the addition of stats file in debugfs that presents driver's statistics (patch 3/7).

Please note that patch 3/7 depends on 2/7 (which also simplifies calculation if tracing is on).

Thanks!
